Tech. Sgt. Ken White, 919th Special Operations Aircraft Maintenance Squadron crew chief, prepares tools and parts needed to install a new propeller on a C-146A Wolfhound, as part of a special maintenance training program March 23, at Duke Field, Florida. The training program is designed to create maintenance specialists to operate interchangeably in deployed locations, keeping crews smaller and saving the Air Force money and manpower.
